Which of the following special symbol allowed in a variable name?
Answer: Option
Explanation:
Variable names in C are made up of letters (upper and lower case) and digits. The underscore character ("_") is also permitted. Names must not begin with a digit.
Examples of valid (but not very descriptive) C variable names:
=> foo
=> Bar
=> BAZ
=> foo_bar
=> _foo42
=> _
=> QuUx

Yes Thiru. Variables should start only with an alphabet or _ (underscore).
Examples:
Valid statements:
int a;
int area2;
int _Sum;
int A_Sum;
int _23area;
Invalid statements:
int 23area;
int @ss;
Examples:

int _23area;
